COCONUT CREEK, Fla. (AP) — The Latest on the commission investigating the Florida high school massacre (all times local):

1:45 p.m.

A father whose daughter died in the Florida high school massacre said an investigative commission will discover the deaths could have been avoided it weren't for egregious errors made by law enforcement and school officials.

Andrew Pollack is one of three victims' fathers appointed to the 16-member commission investigating the Feb. 14 shooting at Marjory Stoneman Douglas High School that left 17 dead, including his 18-year-old daughter, Meadow. The commission held its first meeting Tuesday, hearing from a Broward Sheriff's Office detective who laid out the gunman's actions during the shootings.

Pollack told reporters that the commission would unearth "how much incompetency there was that led to my daughter and the other 16 victims being murdered."

He pointed to the FBI, whose officials have acknowledged they failed to follow up on a warning call about Cruz. In addition, the sheriff's office said Tuesday that deputies had 18 contacts with Cruz before the shooting, but that he never did anything he could be arrested for.

A commission investigating the Florida high school massacre has learned that faulty classroom designs and police radio and 911 systems contributed to the chaos and possibly to some of the 17 deaths.

The Broward Sheriff's Office told the Marjory Stoneman Douglas High School Public Safety Commission at its first meeting Tuesday that teachers couldn't lock their classroom doors from the inside as they tried to lock down their students Feb. 14. They had to open their doors and use a key to lock them from the outside.

The doors also had small windows, allowing the gunman to fire into the locked classrooms.

Broward sheriff's radios were not on the same channel as Coral Springs police, the two primary agencies that responded. Attempts to merge the radio channels failed, preventing the two departments from sharing information. Coral Springs and Broward are also on separate 911 systems. Calls were coming into both.

The Marjory Stoneman Douglas High School Public Safety Commission held its first meeting Tuesday. The 16 members appointed by Gov. Rick Scott will question school and mental health officials.

Commission members include law enforcement administrators, education officials, a state senator, a mental health counselor and the fathers of victims Alex Schachter, Meadow Pollack and Aliana Petty. The members were appointed by Scott, state House Speaker Richard Corcoran and Senate President Joe Negron.
